Examples of factory made 1961 cabinets, both A and B, from the 80's. The vertical mounted style B cabinet is extremely rare and may even be from the 60's. All due thanks to the folks who took these photos as I found them on forums. These 3 pix are the only interior photos of 1961 cabs I could find anywhere! That's how rare they are. But, I have seen one with my own eyes!
